Abstract

The structures of the title compounds, C17H20BrClN2O3, (I), and C17H19ClN2O3, (II), are stabilized by intramolecular C—H⋯O and C—H⋯π interactions. The stability of the molecular packing in (I) and (II) arises from a diverse set of weak intermolecular C—H⋯O, C—H⋯π and C—halogen⋯π interactions. In the crystal structure of (I), mol­ecules aggregate in dimeric subunits via C—Br⋯π interactions. The dimers are interlinked by C—H⋯O hydrogen bonds. The halogens cluster together and form a channel along the b axis. In (II), the packing is mainly governed by intermolecular C—H⋯O and C—H⋯π interactions.
